State and Country Technology Emphasis Report, Corporate Patenting Utility Patent Grants Calendar Years 2003 and 2013

Technology Emphasis As Determined By USPTO Patent Class

Listing of Technology Classes Receiving
1
or More Utility Patents During the 1999 to 2013 Period
Originating From

OKLAHOMA

( patent origin is determined by the residence of the first-named inventor )
( technology class is determined by the primary classification assigned to the patent- see 'Explanation of Data' )
( a class in which 200 or more patents were granted in 2013 is identified with a 'Y' in the 'Active Class' column )
( a higher activity index indicates a higher technology emphasis; table is sorted by descending 2013 Activity Index )

This table includes counts and activity indexes that display technology emphasis by technology class and calendar year. Counts are for utility patents originating from the selected region.
